eLoran Appears Doomed Despite Possible GPS Backup Role

Enhanced Loran (eLoran), the proposed backup to GPS that has made a career out of surviving efforts to eliminate its Loran-C foundation, now appears to be only two signatures away from extinction — and both appear likely.

A House-Senate conference committee version of the fiscal year 2010 (FY10) appropriations bill for the Department of Homeland Security (DHS) approved October 7 allows for termination of the Loran-C signal on January 4, 2010.

U.S. Congress Working on 2010 Appropriations for Loran-C and eLoran as GPS Backup

Enhanced Loran (eLoran) has survived through multiple generations of official ambivalence about the proposed backup for the U.S. Global Positioning System. Currently, the program is in (almost) on-again status.

The latest chapter began with President Obama’s Fiscal Year 2010 (FY10) budget proposal, which called for termination of Loran in the coming year. At a May 7 press conference, the president described Loran as a system that’s been eclipsed by the rise of GPS.

eLoran: The Never-Ending Story?

To say that enhanced Loran (eLoran) has been an on-again off-again program would give short shrift to multiple generations of official ambivalence about the proposed backup for GPS.

The latest chapter began on June 4 when Senator Maria Cantwell (D-Washington) introduced S. 1194, the Coast Guard Authorization Act for Fiscal Years 2010 and 2011 (FY2010/11).

Among other details, the measure directs the Secretary of Transportation to continue the Loran system until a plan has been drawn up and implemented to transition the program to eLoran.

FY 2010 Budget Outline Proposes to End Loran

Ready for another round?

President Obama appears to have weighed in on the long-running Loran/eLoran debate — on the side of terminating the terrestrial radionavigation system and, apparently, its enhanced version that had been proposed as a backup to GPS.

In a February 26 message to U.S. Coast Guard (USCG) members, Vice-Admiral V. S. Crea, USCG Vice Commandant and Chief Operating Officer, said the Fiscal Year 2010 (FY10) budget outlined in a document sent to Congress calls for termination of Loran-C in the coming year.

President’s 2009 Budget Proposal Directs DHS to Implement eLORAN

The Bush administration appears to have finally made a long-delayed decision to complete implementation of an enhanced LORAN (LOng RAnge Navigation) system to serve, in part, as a back-up to GPS.

Late in the drafting process of the Fiscal Year 2009 (FY09) budget proposal that went to Congress earlier this week (February 4), officials added language “migrating” the LORAN-C system from the U.S. Coast Guard (USCG) to the Department of Homeland Security’s National Protection and Programs Directorate (NPPD). A $34.5-million budget and 294 positions would take part in the migration.

Loran Revives; NDGPS Fades

The Loran terrestrial radionavigation system might well be pulled back from its 12-year-long dance on the brink of extinction, while the Nationwide Differential GPS (NDGPS) radiobeacon-based augmentation system may have finally been pushed over the edge.
